Ukukhubazeka kwekhwalithi yamapayipi adonswa ngokubanda kanye nokuvimbela

Ipayipi lensimbi engenamthungo izindlela zokucubungula ezibandayo:

①ukuginqika okubandayo ②umdwebo obandayo ③ukuphotha

a. Umdwebo obandayo ogoqayo nobandayo usetshenziselwa ikakhulukazi: ukunemba, udonga oluncane, ububanzi obuncane, amapayipi ahlukene angavamile kanye namandla aphezulu.

b. Ukuphotha kusetshenziselwa ikakhulukazi: ukukhiqizwa kobubanzi obukhulu, udonga oluncane noma ububanzi obukhulu kakhulu, amapayipi ensimbi odongeni amancane kakhulu, futhi kunokuthambekela kokushintshwa kwamapayipi ashiselwe (umcu wensimbi, ukushisela, ukwelashwa kokushisa, njll.)

Ukugeleza kwenqubo eyinhloko yokukhiqiza amapayipi ensimbi angenamthungo ngomdwebo obandayo:

Ukulungiswa kwepayipi elingenalutho → Umdwebo obandayo wepayipi lensimbi → Ukuqedwa nokucutshungulwa kwepayipi lensimbi eliqediwe → Ukuhlolwa

Izici zamapayipi ensimbi angenamthungo akhiqizwa umdwebo obandayo (uma kuqhathaniswa nokuginqika okushisayo)

① Ububanzi bangaphandle bepayipi lensimbi buba buncane kuze kube yilapho sekukhiqizwa amashubhu e-capillary

②Udonga lwamapayipi ensimbi luzacile

③Ipayipi lensimbi linobude obuphakeme bokunemba kanye nekhwalithi ephezulu yendawo

④Umumo we-cross-sectional wepayipi lensimbi uyinkimbinkimbi kakhulu, futhi izingxenye eziphambanayo eziguquguqukayo kanye namapayipi ensimbi anomumo okhethekile angakhiqizwa.

⑤ Ukusebenza kwepayipi lensimbi kuphakeme

⑥Izindleko zokukhiqiza eziphezulu, ithuluzi elikhulu nokusetshenziswa kwesikhunta, izinga lokukhiqiza eliphansi, okukhiphayo okuncane, nezimfuneko eziphakeme zokuvikela imvelo

Ukukhubazeka kwekhwalithi yamashubhu adonswa ngokubanda kanye nokuvimbela kwawo

⒈ Ukukhubazeka kwekhwalithi yamapayipi ensimbi adonswa ngokubanda ikakhulukazi kuhlanganisa: ukushuba okungalingani kodonga lwamapayipi ensimbi, ububanzi obungabekezeleleki bangaphandle, ukuqhekeka kwendawo, imigqa eqondile kanye nokuklwebheka, njll.

①Ubukhulu bodonga obungalingani bamapayipi ensimbi adonswa ngokubanda buhlobene nokunemba kogqinsi lweshubhu elingenalutho, indlela yokudweba, i-centerline yokudweba, ukwakheka kwembobo, imingcele yenqubo yokuguqulwa kanye nezimo zokuthambisa.

a. Ukuthuthukisa ukunemba kokuqina kodonga lwe-tube engenalutho kuyisidingo esibalulekile sokuthuthukisa ukunemba kodonga lwepayipi lensimbi elidonsa abandayo.

b. Inhloso eyinhloko extubation ngaphandle mandrel ukunciphisa ububanzi kanye deformation

c. Ukwakheka kwembobo kuyisici esibalulekile esithinta ukushuba okungalingani kodonga lwamapayipi ensimbi adonswa abandayo.

d. Futhi kuyindlela ephumelelayo yokuqinisekisa ikhwalithi yokukhetha ye-tube engenalutho, susa isikali se-iron oxide ebusweni bayo, futhi uthuthukise ikhwalithi yokugcoba.

②Ngesikhathi senqubo yokukhiqiza, kufanele kubhekwe ukunaka okukhulu ekugugelweni nasekudabukeni kokufakwa nokubhala

③Ukuze kuncishiswe imifantu ebusweni bepayipi lensimbi ngemva kokudonsa, izikhala zamapayipi ezifanelekayo kufanele zikhethwe, futhi izici ezingaphezulu kwezikhala zamapayipi kufanele zigaywe. Lapho ucosha izikhala zamapayipi, kuyadingeka ukuvimbela ukukha kakhulu ukuze ugweme umgodi noma i-hydrogen embrittlement, futhi Ukuze uvimbele ukucosha phansi nokuhlanzwa okungaphelele kwesikali se-oxide, qinisekisa ikhwalithi ye-anneal yeshubhu elingenalutho ngesikhathi sokusetshenziswa, sebenzisa okunengqondo. indlela yokudweba i-tube, khetha imingcele yenqubo ye-deformation efanele kanye nesimo sethuluzi, futhi uqinise ukulungiswa nokuhlolwa komugqa wesikhungo somdwebo.

④Ukuthuthukisa ikhwalithi yokukhetha kanye nekhwalithi yokuthambisa yepayipi ingenalutho, ukuqinisekisa ukuthi ithuluzi liqinile, ukufana nokuqedwa kwendawo kuzosiza ukunciphisa ukwenzeka kwemigqa eqondile kanye nokuklwebheka epayipini lensimbi.
